The next morning you wake up to a throbbing cock and aching balls, indicating that there was no release last night despite your sexual escapade. Silvia starts kissing your neck causing you to start pushing your cock closser to her. "I have an idea to help you deal with your aching crotch hon. I was asking the preacher about it and she told me to try this!" She reaches around the nightstand and pulls out a small chastity device, "whats that for?" You ask, not having seen one before. "Its going to go around your privates, and keep you from the temptation of spilling out your seed too much. You know, the seed that needs to only be planted in me! Here, let me put it on!" And with that she puts some lube onto the device and her hand and starts to go under the covers. You feel a slight stimulation from her hand on your cock, which makes your balls recoil in hopes of getting to release the unspent cum. You feel a slight hit against your balls, which feels almost like slapping, and you start to object. "Sorry honey!" Silvia replies from under the covers, "but i needed to get your erection to go away in order to fit the cage on!" And with that you feel the ring go around the base of your genitals, and the cage slide onto your cock, giving you slight pleasure from the lubed up tube encircling your sensitive cock. Before you can enjoy to get hard though, you hear the click of the lock go in place, and the expanse of your cock does nothing more than tug on the ring holding your testicles in place.
